7 10 all whom 'it may concern:

Be it known that I, ALFREDO Scorri, a subject of the King of Italy, who 'have declared my intention of becoming a citizen of the United States, residing` at hittier, in the i county of Los Angeles and State ofr California, have'invented new and useful Tractionlheels, of which the following is a specilication.

My invention relates to traction vehicles, being more particularly a traction wheel for traction vehicles such as are used for haul.n ing farm implements of various kinds. Vehicles of this kind are used for different kinds of work upon ground of Vvarious types, that is, the same vehicle may be required to pull a load over sandy soil, heavy soiLand in some cases where the surface isA hard.

The principal object of my invention is to provide a traction wheel of the class described which will be efficient when used upon any of the various types of ground.

Other objects and advantages will be made evident hereinafter from the following description. 1

Referring to the drawings which are for illustrative purposes only,

Figure 1 is a side elevation' of a traction wheel embodying a'form of my invention.

Fig. 2 is a verticalsectional view of the wheelshown in Fig. 1.

Fi 3 is an end view of the vwheel shown in Fig. 1, and

Fig. 4 is a vertical sectional view of half ofthe wheel, showing a modified forni of my invention. l

The wheel, in the form shown, is made of a single casting, but it is .understood that the parts of the Wheel may be made separately and secured together in any of theV ywell known common practices in making similar devices. The wheel consists of a hub 11 and a series of radially extending spokes 12, which spokes are in the form ,of at plates having a shoulder 13 thereon upon which is seated a rim 14. The spokes are disposed almost wholly to one side of thev rim 14, the rim being on the inner side ofthe wheel. The spokes 12 each extend beyond the rim, such extended portion 15 of each spoke forming a flight or traction means for engagingv the ground. On the outer side of the spokes is preferably arranged a bar or bridge 16 forming a rib of less diameter than the rim connecting the spokes for the purpose of strengthening the same. Each spoke is prefy erably cutaway as indicatedat 17 for the purpose hereinafter described. f

In the form shown in Fig. 4 the spokes 20 support two rims 21 and 22, the spokes having an extension 23 which extends beyond the rims and forms the flights for the Wheel. In using wheels of the construction above described the flights 15 extendinto the ground varyingdepths according to the character of the ground. In the Ordinar ground foundin orchards and the like t e flights extend into the ground and almost wholly support the weight of the vehicle, the rim .14, however, riding upon the surface of the vgroiind therebyv preventing a too great penetration of the flights into the surface of the ground.y

There the ground is sticky and wet, in ordinary types of traction wheels there isa tendency for suoli ground to pack between the flights upon the rim of the wheel and in a very short time the spaces between the flights are almost entirely filled with the packed dirt and they wheel assumes the shape of an ordinary flat rim thereby destroying the traction efficiency of the wheel. In using -my wheel abovek described in such ground,

however, there is no opportunity for the dirt topack betweenthe flights as the space between the flightsis entirely clear, the dirt f, passing between the flights, and should the dirt extend farther into the kwheel between yond the rim.

2. A traction wheel comprising a hub, a

. rim, and aseries of spokes consisting of Hat members extending beyond the rim, said rim vbeing at the side lof the extended portion of said spokes and narrow in proportion to the width' of the extended portion of the spokes. 8. A traction wheel comprising a hub, a plurality of spokes terminatmg at their outer ends in flat plates forming flights, and a rim at the side of said flights.

4. v.In a traction Wheel, a hub, a rim, spokes connecting said rim `to the hub, and e series rim at one side thereof, and a rib of less diof flights at one side of said rim extending ameter than said rim connecting said spokes outwardly therefrom.` on the side thereof opposite to the rim. l0
